C. Rabauti

[all_waze]

Received 5 rabautis about a week ago out of a many week import quarantine. they didnt look too bad considering and all started eating fairly soon after intro to their tank. anyways, a couple days back noticed a white patch on 3 of them just behind the right eye. nothing fuzzy or anything might just be missing skin and a coincidence. the patch is slightly whiter than on the pic. any ideas?

Firstly I don't think your fish are C. rabauti, but C. zygatus, They are similar in looks but C. zygatus grows to about 3 inches. The white patch looks like it could have been caused a parasitic infection, resulting in a secondary bacterial infection. You say that the fish came to you after a long quarantine. If this is so this problem should have been eradicated, but I would quite honestly question the long quarantine. I would treat the fish with an anti bacterial medication and maybe even for parasites just to make sure.

Thnx for the input. I got the rabs from a pretty reputable importer here in the states..not saying they can't make mistakes. I looked at the zygatus and truthfully can't see much difference, at least nothing that jumps out. Maybe its a region thing? In any case, I emailed them questions as you had suggested and asked them to differentiate rabs from zygs. As soon as I hear back from them I will let you know. Regarding the white area...doesn't seem to be progressing any at least not now.

What size is the fish? As that seems to be the difference.

While I am sure Ian would never claim to be infallible, he is one of the most experienced Cory people in the world and has written the book on Cory IDs--literally.

Ian....heres the response from the importer. Whatcha think?

"Jim,

No, the issue here was the weren't eating as well as I like when we release them. We have to have them eating a varied diet which can be problematic for many species as they all prefer and want live bloodworms over everything else which is not conducive to many buyers so if they stop eating tablets and such I will hold them off food a few days and force them onto pellets, etc which is what we did.

As for the issue, hard to say without seeing it but we treat with a wide variety of medications including Parinox, TMP Sulfa Powder, Nitrofuracin Green Powder, Quinine Sulfate Powder, Paracide-D, Metronidazole Powder, Sulfa 4 TMP, Gentamycin Powder, Doxycycline Hydrochloride and Praziquantel to name a few of the most common medications we use. All are treated on arrival for internal and external parasites as well as prophylactically for bacterial (both gram negative and gram positive), viral, and fungal issues. If it appears to be a fungal issue and not water quality related then I would recommend Griseofulvin Powder along with Doxycycline Hydrochloride for the secondary bacterial infections.

Lines crossing the body length finish on the top half of the plate intersection at the base of the caudal peduncle. In C. rabauti this line crosses the plate intersection and finishes at the bottom of the bottom row of plates. Unless you know the locale of the collection it is quite difficult to discern the difference and even then there are color variations within the two species which make it even more difficult to discern the two species apart."
